and evenly fed from their take-off Aspools without necessity for-anytension or brake devices upon said spools, which would be a loadupon the machine, and thereby further the tendencyv of the core strandsto twist from lthe jaws 105 backward/ly to said take-olf spools iseffectually resisted and the 'two f'core strands are maintainedabsolutely straight, which is very desirable lin the case vof a cablethe wrapping of which is formed rof twisted wires. The core strands 832,are formed respectively of two wires tightly twisted together, as forinstance inthe machine of my cci-pending application S. No. 641,636,-filed May 26, 1928, for machine` for 1nanufacturing wire cable. f

The 'shaft 104 has mounted thereon to revolve therewith a plurality 'ofAtake-off spools 88, from which the wire strands or sub.-

sidiary ropes 83y (also double in the present .r instance as disclosedin my said co-pendingy application and in a second co-pendingapyplication filed June 8, 1923, S. `No.',644,254)

converge Aand pass through passages 109 -of -said shaft, saidfpassa'gesstarting c'ircufmfer.` "entially of said shaftandV being first inclinedtowards eachother or converging and then assuiriing'parallel relationllongitudinal Vof the shaft and opening atV the vend of the shaft, whichrotates'in bearings 110.

Adjacent said end of the shaft 104 is astation'ary frame includingthertwo jaws "105 aforesaid, spaced from the end Lvof ysaid shaft -at111, and between whichall Vvofjfthe wires 'or subsidiary ropes passincluding the cores 83, 832 and thelconcentric strandsfor ropes 1 Thewire strands or subsidiary ropes being arranged asy stated, and theshaft 104 set 1n rotation to revolve the strands 83Y, relative to thejaws 105, (the latter gripping the wire strands or ropes 832, 83y andholding them against rotation) the wire strands y835 surrounding thecore strands or ropes 83Z will betwisted around said "core, the twistingtaking place in the interval 111, between the jaws 105 and the end ofthe shaft 104, and tension being now^exerted upon thewire strands orropes to continuously pull the same through between said jaws, the wirestrands or ropes will be progressively'twisted to form a still largerrope .83". i

The larger rope so formed anddesignated 83X, now passes around guidepulleys 112, fand thence reversely through a central longitudinalperforation 113 of a second rotary shaft 114, parallelto the shaft 104,and whereon are mounted to revolve therewith a plurality of take-offspools 83, from which the wire strands or subsidiary ropes 83W, pass inconvergence first through guides 115, and thence being more sharply bentand converging, through longitudinal passages 116 Y,of said shaft, saidpassages starting circumferentiallyof said shaft, converging andbecomingparallel and terminating and opening at the end of the shaft,which rotates,`

. stated and the shaft 114 set in rotation and tension exerted upon thestrands or ropes to continuously pullthe same through between the jaws118,'the latter 'gripping the ropesv or strands to hold themagainstrotation, the. strands 83W will be twisted around said core,V thetwistingvtaking place in the interval 120 between said jaws and the endof Saidshaft, anda still larger rope ,83v

' jbeing thereby formed, which-enters` and passes betweenvthe jaws 118continuously.

The-wires 8 3W maybe single strands or composed' ofy two .or morestrandstwisted t0- Vgetlier, being 'in the present instance prefer- Yably composed of two strands twisted together as in my aforesaidcopending application. Y' 4 t,

1 The still larger orcomplete cable formed as `stated passes from-'thejaws 118 under guide pulleyv 122, thence upwardly over guide pulley 123,thence downwardly around vguide pulley 124, carriedbye-block 125gfhavingthreaded engagement ywithscrew rod 126,

Y the complete cable.k

the cable thence passing to the receiving drum 127, whereon it is wound,the rotation of this drum, which is positively driven, as will bepresently described, serving to exert the aforesaid tension upon boththe core cable 83X and the complete cable 83".

The distributor screw rod 126 is threaded in a single direction, as isalso the block 125 thereon, and the direction of rotation of said screwrod is automatically reversed at intervals to cause said block to travelback and forth'of the drum 127 to properly distribute the cable thereon.i

The drive is through main drive shaft Y104, having fast and loosepulleys 128,( and nection 137 with the distributor screw rod 126, and asecond sprocket gearing connection 138 with said screw rod, one or theother sprocket gearing 137 or 136 being Vadapted to rotate said threadeddistributor rod in one or the other direction at intervals as the block125 reaches the end of the distributor rod in either direction ofmovement of said block. y

Owing to the fact that the shaft 104 has a single longitudinal centralaperture 103 for its entire length and at one end portion thereof aVplurality of short longitudinal apertures 109 adjacent to and parallelto each other and to said central'aperture, it is possible to form theshort apertures 109 completely within and with all walls thereofintegral of said shaft 104, and to bring said short-apertures 109 closerto the central longitudinal aperture or passage 103, which is ofadvantage in bringing the wire strands or ropes closer together inparallel relation prior to Ytwisting the same together to form Owing tothe fact that the take-off spools V83 are arranged in series one behindkthe other around the shaft 104, with their longitudinal axes radial ofsaid shaft, it is inade possible to bring said spools closer to eachother and to the' short apertures or vpassages ilo 109 of said shaft,whereby the wire strands or ropes passing from said spoolsV to saidpassages have shorter lengths lthereof eX- posed, which reduces dangerof entanglement'or breakage and whereby the machine is renderedmorevcompact.

A modification of the invention isshow in the drawings wherein there isprovided at the opposite side of the Vmachine from the shaft 104, aseries of short stubjshafts 141, 141% 1411, 141?, 1411, in line witheach other, the endmost of said stub shafts in rear being izo discorsoprovided with two kopposite take-off spools 142, removably securedthereon and thewire strands 143 therefromv passing towards each other,as shown in Figure 3 of vthe drawings to guide pulleys 144, and thencepassingforwardly to points diametrlically opposite and adjacent 'saidshaft 141 and entering short passages 145 atlone end portion of saidshaft, said passages starting circumferentially of the shaft and beinginclined and then assuming parallel relation longitudinal of the shaft(see Fig. 5) and ending and opening at the forward end of thestub-shaft. the latter rotating in bearings 146.

Adjacent the fo-rward end of the stubshaft 141 is a stationary frame147, including two opposite. jaws 148, one of which is pivoted at 149,and the. jaws being held together yieldably by spring 150, and spacedfrom the end of the shaft 141 at 151, said wire strands 143 afteremerging from the end of the shaft 141, passing between said jaws, andtension being exerted upon the forward ends of the wire strands as willbe hereinafter explained to continuously pull the saine through betweenthe jaws 148,

and the shaft 141 being set in rotation, the result will be that thewire strands will be twisted together in the space 151 to formcontinuously a core cable 152. This core cable 152 being formed` asstated enters immediately a central longitudinal perfora tion 153 of thenext stub-shaft 14111k in line,

which shaft is similarly provided with takeoff spools 1421, deliveringtheir wire strands 143au to guide pulleys 14411, to short passages 145aof the stubi shaft and to aws 1481, all as aforesaid for the first namedstubshaft2 the core cable 152 being delivered to said jaws centrally ofthe wire strands 14311, which latter will be twisted continuouslytherearound, following rotation of the shaft 141EL and exertion oftension as previously stated, to form a larger cable 1523.

The stub-shafts 1411, 141, 14111, following consecutively in line aresimilarly provided respectively with central longitudinal perforations15311, 1531, 153, and with take-off spools 1421), 142, 14211, deliveringtheir wire strands 1431, 143, 143L1 to guide pulleys 14411, 144C, 14411,and to short passages1451, l145C, 14511, of the said stub-shafts and tojaws 1481, 148C, 14811, related to the stub-shafts.

The cable 1521*, is delivered from the jaws 14811, related to theseco-nd named stub-shaft immediately to thev central longitudinalperforation 153a of the stub-shaft 1411,neXt in line, and the wirestrands 1431, being twisted thereariound in the manner explained, a

i still larger cable 1521), will be formed, which has in turn the wirestrands 143d twisted therearound following the passage of the cable 1521through the longitudinal central perforation of the stubeshaft 14111, toform The cable 15211, now passes around guide pu'1leys154 and thencearound guide pulley 112, adjusted vto ldotted line position, Figure 1,andiis delivered to the central 'per- -foration 113 of the shaft 114aforesaid in substitution of theL cable 83X aforesaid and tofform .acore for the wire strands or .subsi'diary ropes 83w aforesaid, thelatterbeing twisted around the cable 15211 to form a modified form ofcomplete cable 83, the core 152d of which is shown in diagram in crosssection in Figure 17.

As a result of this modification, a core cable 143 is twisted and fed tothe machine i by means forming a part of the machine, and the completecable is-.built up progressively by concentric layers of twistedstrands. V

The stub-shafts 141, 14111, 1411), 141e7 14111, are respectively rotatedby chain connections 155 with a longitudinal shaft 156 driven at. 157from the shaft 114.
